Here are the main sources of help with QuPath questions:
- This documentation, including FAQs
- The Command List & its built-in help
- forum.image.sc - main user forum, shared with other open source projects
- Issues on GitHub - bug reports, not general questions
- YouTube channel - includes video tutorials (still mostly for v0.1.2) and webinars
- Twitter - most things will be announced here first
There’s also a fantastic forum post introducing QuPath from a user’s perspective here.
If your needs for instruction are more modest, it’s always worthwhile to try hovering your mouse over nearby buttons or input controls - there’s a good chance that an explanation will pop up to explain what the control does.
